Bass Pod Xtlive Model Output Problem

Hi. My new Bass Pod Xt live is not working well. The model output seems that is not working. There´s sound but there´s no sound of modeling amps. The pedal volume dont work, when i put it to zero the volume dont change. The chan volume knob doesnt work properly too. Otherwise, when i put plug the phone in the output phone, the sound modeling its ok. The effects are running ok too. The only problem is that i can´t have a modeling amp sound. Whats going on? Im using the original power supply and i recall the factory settings, but the problem continues.
